Intrusion Detection — CompTIA Security+ (SY0-701) Practice Questions

Intrusion detection is the practice of monitoring systems and networks to identify unauthorized access attempts, policy violations, or indicators of compromise in near real time. On SY0-701, intrusion detection is covered as part of security operations and includes both automated tools (IDS, SIEM) and manual analysis techniques such as log review and behavioral analytics. The exam tests candidates on detection methods, placement of sensors in the network architecture (inline versus out-of-band), and how intrusion detection feeds into incident response workflows. Understanding the relationship between intrusion detection and intrusion prevention, as well as the role of threat intelligence in improving detection accuracy, is essential for exam success.
